Maybe I am just not a good enough player, but I get to a couple of boss battles that I just can not win. I intend to explore a bit more to try to get powerful and then have another go at them. The problem with that is that you have to play the same parts over 10-12 times (until the enemies no longer respawn) to build up your skills. Graphics are good but NPC interaction is poor. Also it is not an open world just a well camoflaged corridor with a some well decorated larger rooms if you do not fight the enemy in front of you can not continue on the game.
Some will disagree but i think it needs a way of reducing difficulty at some points, Even if it just helps you after the three sentinals have killed you for the 20th time.
In the end this is promises a lot but is a boring, no plot, no story, just killing the same enemies at the same place with the same 3 moves over and over again, it did not give me anything, its no skyrim or even far cry.
